To all wgwin it may concern: H

Be it known that I, WILLARD E. Grieve- LAND, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have 'invented a new and Improved Stop for Phonographs, of which the followingis a full, clear, and exact description. f

The invention relates to phonographs of the disk record type, and its object is to pro vide a new and improved automatic stop arranged to automati'call stop the honograph at the time the sty us reaches t 0 end of the and to allow quick and convenient adjustment of the automatic stop for larger and. smallerrecords.

In order to accomplish the desired result, use is madeof .a pin on the tone arm controlling an actuating rod pivotally connected with a trigger engaging a springpressed brake lever adapted to engage the revolving platform whenever released by the trigger to stop the rotation .of the said, platform, Use'is alsogn ade of a trigger consisting of l 26 two levi-sconnected with each other by a friction pivot allow of adjusting one lever.

relatively to the other, the adjustable lever being controlled from the vtone arm and the other leverbeing controlled from the brake inechanisrn of the phonograph,

A practical embodiment f the mvention is represented in the accompanying draw ings forming a part of this spfecifieatiiin, in

a which similar characters of reference indi cate' corresponding parts in all the views.
